Background Residents are being asked to perform educator roles such as curriculum design and learner assessment with minimal professional development in leadership or medical education. The Multidisciplinary Academic Day (MAD) planning committee is a resident-led initiative responsible for delivering combined educational half-day sessions and workshops for all residents at McMaster University. Objective We sought to determine the impact participation in MAD planning committee had on residents' professional development and career goals.  Methods We conducted a program evaluation survey of 19 of 30 (63.3%) current and former committee members to determine how the MAD planning committee's alumni perceived its usefulness, and how participation affected their professional development.  Results Residents cited a desire to gain medical education experience, learn about event planning and management, and improve resident education as reasons for joining the committee; 89.5% of respondents felt they had met these goals. Experience on the committee included skills related to curriculum design, developing needs assessments and programmatic evaluation. Many residents felt it helped them acquire leadership skills such as decision-making, idea generation, delegation, and public speaking. Several noted that it had sparked an interest in medical education as part of an academic career, and one former member subsequently pursued a Master's of Education. The majority of the respondents (78.9%) felt it was helpful for their careers and 94.7% would recommend this experience to others interested in leadership and medical education.  Conclusion Involvement in the MAD planning committee is a highly useful way for residents to acquire leadership skills, develop an interest in medical education and work in a multidisciplinary team.
